Golden Rim Resources Ltd (ASX: GMR) has uncovered diamond drill core from historical work done at the Falun Project in Sweden.
Previously in private ownership, the assays were from samples taken by the Bergslagen Joint Venture of underground diamond drill core from the past mining operation before 1992.
These have been from depths of between 200 and 400m below surface. The new assays were taken from six archived holes and returned high grade results with gold up to 43 g/t, copper up to 2.24%, bismuth up to 2.4%, and selenium up to 0.425%.
From the results the company believes there is growing evidence of a link between the high-grade gold-copper mineralisation drilled recently by the BJV and the previous gold mining operation on the 350m level.
The company will add the new assays to their resource estimation database.
There appears potential for significant volumes of remnant gold and copper mineralisation to be outlined around the old mine, a positive for Golden Rim Resources.
